Wärtsilä two-stroke engines have been chosen for eight Chinese bulk carriers. The order was placed by Beijing-based Minsheng Financial Leasing; Wärtsilä's Chinese licensee, Hefei Rong'An Power Machinery (Rong'An), a member of the Jiangsu Rongsheng Heavy Industries Group (RSHI), will build the engines.

The Wärtsilä 5RTFlex58T-D two-stroke engines will be installed in a series of eight 76,000 dwt Panamax bulk carriers. The first vessel is scheduled to be launched in March 2011.

"The main reason for our choice of Wärtsilä RTFlex58T-D main engines for our Panamax bulk carrier project was the good reputation, in terms of reliability and excellent performance, achieved by this engine type," said Dr Wang Keke, head of leasing department 1 at Minsheng Financial Leasing.

The Wärtsilä RT-flex engines, with their claimed superior common-rail technology, are said to offer a number of direct benefits to ship owners and operators. These include fuel efficiency, flexibility in engine setting for lower fuel consumption, lower minimum running speeds, smokeless operation at all running speeds, and control of exhaust emissions. The RT-flex engines comply with the reduced NOx emissions requirements of the IMO Tier II standard, which will become effective from 2011.

According to Wärtsilä, the MCR of this engine is 11,300 kW at 105 rpm, and the engines for the first four ships in the series will be fitted with are fitted with standard turbochargers, but other ships in the series will be equipped with high-efficiency A type turbochargers supplied by ABB. A Wärtsilä spokesman told The Motorship that the company is confident that this will be a long series.

Minsheng Financial Leasing is a subsidiary of China Minsheng Banking Corporation. The vessels now on order will be the first to be purchased by the company.

The bulk carriers will be built in Nantong, China by Rongsheng Shipbuilding & Heavy Industries, part of RSHI. RSHI runs China's third-largest shipyard and is the country's largest private shipbuilding group; its order book currently consists of 83 vessels. Equipped with two large dry docks, RSHI is able to build a wide variety of vessel types, including bulk carriers of Panamax size and larger, tankers from Aframax to VLCC sizes, LPG and LNG carriers, and container ships of 4250-9700 TEU.

In 2008, Wärtsilä signed a licence agreement with RSHI, the parent company of Rong'An, to manufacture Wärtsilä low-speed common-rail engines. At the end of 2009, Rong'An delivered its first six-cylinder Wärtsilä RT-flex68B engine to Brazil's Log-In Logistica Intermodal and currently has orders for a further 12 seven-cylinder RT-flex82T engines.

Wärtsilä will provide operator training for the ships' crew members. Wärtsilä has a dedicated training facility in Shanghai that can also offer the courses in Mandarin language. The facility boasts complete engine room machinery, among them a state-of-the-art control room simulator for the RT-flex engine, a rail unit section, injection control units, and a fuel supply unit to provide practical, hands-on training possibilities.
